Abstract

A method and an apparatus for electrical contacting of cells of a battery. The method includes: using a laser beam having a first beam energy to remove contamination in a region, provided for electrical contacting, of an electrically conductive outer surface of a first cell of the battery; using a laser beam having a second beam energy higher than the first, to generate at least one marking in the outer surface of the first cell, the marking having a predefined spatial relationship to the region provided for electrical contacting; and electrically contacting the first cell using a connecting apparatus, the marking being used by the connecting apparatus to localize that region of the first cell which is provided for electrical contacting in order to connect said region by way of an electrically conductive connecting element to a region, provided for electrical contacting, of a second cell of the battery.
